c++ replace a set of strings between << >> delimeters

Question

I want to replace a set of strings between << >> delimiters.

For example say

int age= 25;
string name= "MYNAME";

string test = My age is << your age >> and my name is << your name >>.

Output should be

My age is 25 and my name is MYNAME.

What is the best method to do this is c++ ?

I don't quite understand your question. Why do you want to use these "delimiters" exactly? — Jérémi Panneton, Mar 09 '15 at 05:50

try this

#include <iostream>       
#include <string>        

int main ()
{
  std::string str ("My age is << your age >> and my name is << your name >>.");
  std::string str2 ("<< your age >>");
  std::string str3 ("<< your name >>");
  str.replace(str.find(str2),str2.length()," 22 ");
  str.replace(str.find(str3),str3.length()," Nooh ");
  std::cout << str << '\n';
  return 0;
}

Im not sure I understand the question, but if its what I think it is, try

string test = "My age is " + age + " and my name is " + name + ".";

If you are bent on using << and >>, you can do

cout << "My age is " << age << " and my name is " << name << "." << endl;

c++ replace a set of strings between << >> delimeters
